Does anyone know how long it takes tadpoles to get legs?

Question

How long it takes a tadpole to become a frog?

Answer 1

Alot shorter of a time period than what it will take for you to grow a brain.

Answer 2

Most frogs undergo a two-stage life cycle. Eggs hatch into fishlike young called tadpoles, which grow and eventually undergo metamorphosis, a change in body form, to become adults. Frogs have developed many variations on this common theme, and a few species provide striking exceptions to the rule. For example, frogs in the tropical genus Eleutherodactylus do not have a tadpole stage. Instead, tiny froglets hatch directly from the eggs. In the African toad, fertilization occurs internally, and the young are born alive.

Frogs often produce large numbers of eggs—up to 10,000 or more—surrounded by a jellylike coating that protects the eggs from predators and keeps them from drying out. Those that provide some degree of care for their young usually produce relatively few eggs. Species that breed in ponds typically lay their eggs in clumps or strings in the water. Those that breed in streams often attach their eggs to the undersides of rocks. Others construct foamy nests in the water or on vegetation near the water. Some frogs even attach their eggs to the undersides of leaves that hang over the water. When these tadpoles hatch, they drop into the water below. Many species lay their eggs in water trapped in tree cavities or cup-shaped parts of plants. In warmer climates, eggs may hatch within 1 or 2 days, while in colder environments they may take 30 to 40 days to hatch.


Becoming a Frog






Becoming a Frog
The legless tadpoles that hatch from a floating mass of frog eggs are the animal’s fishlike larval stage. Part of a true metamorphosis, they have gills and a tail, both of which disappear as the tadpole feeds and grows. When limbs and air-breathing lungs develop, the young frog, now a miniature replica of its parents, emerges from water to land.

Tadpoles, which usually live in water, look somewhat like small fish. A tadpole has an oval body, gills for breathing, and a long, muscular tail with fins along the upper and lower edges for swimming. Tadpoles have two small eyes, one on each side of the head. A tadpole’s mouth has a horny beak and rows of tiny, comblike teeth that the animal uses to scrape algae from underwater plants and bite off bits of plant material. In a few species, tadpoles eat the eggs and tadpoles of other frogs. Tadpoles pump water through their mouths, over the gills, and out through an opening called the spiracle, which is usually located on the left side of the body. The gills extract oxygen from the water. The tadpole stage lasts anywhere from a few weeks in species that lay eggs in temporary ponds to three years in the bullfrog. Typically, frogs spend a few months as tadpoles before metamorphosing into adults.

Metamorphosis involves radical changes in both external and internal body parts. The tadpole grows legs—the hind legs appear first—and resorbs its tail. It loses its gills and grows lungs, and the structure of the heart, digestive system, and skeleton changes. The horny beak and other mouthparts adapted for eating algae disappear and are replaced by the long, sticky, projectile tongue that helps adult frogs catch insects. Frogs reach reproductive age anywhere from several months to several years after metamorphosing. Most frogs probably live only a year or two in the wild, but bullfrogs live several years, and the African clawed frog has been known to live 35 years in captivity.

Answer 3

Maybe 6 months or a year.

Answer 4

Depends on the species. Sometimes up to three years!

Isn't it like 3 months?
